Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed May 28, 1902,. Renewed August 15,1906 Serial No. 330.740.

My invention relates to calculating-machines, and particularly tothe class of calculating-machines designed and intended to be used in connection with a type-writing machine for adding numbers as they are printed by the operation of the numeral-keys. A machine of this class forms the subject-matter of United States Patent No. 712,881, granted to me October 28, 1902.

The machineof the present application in general features of construction and opera tionis similar to the machine of my patent, comprising, broadly, a construction adapted to be readily connected to the frame of a type-writing machine carrying calculating mechanism adapted to be operated by the numeral-keys only when the aper-carriage has reached 'a predetermine point in its travel, the numeral-keys being adapted to be operated to print without times during the travel of the paper-carriage except when the carriage has reached such predetermined point in its travel.

A particular featureof the machine of the present application is the construction by which in the operation of the calculating mechanism by the numeral-key the opera tion of the registering mechanism is efiected before the key has completed its stroke and the registering mechanism disconnected from the key, so that before com letingits stroke the key is freed from the a dditionalload of the registering mechanism, and in cfl'ecting the printing of its character its action is unimpeded, with the result that it prints its character as clearly as does any oft e letter keys.

the registering mechanism throughout its stroke itshctionon its typebar is sluggish, with' the result that the type bar is pushed rather than impelled to the printing-point, causing, a blurring of the effecting the operation of the calculating mechanism at all actuating Where the numeral-key carries the additional load of S- print. The disconnection of the registering mechanism from the key permits the key to return quickly when released, the registering mechanism being returned independently, and thus permits of the operation of another key or a second operation of the same key to be ei iected at once without waiting for the return of the registering'mechanism to normal position.

A further feature of the invention of the present application is the construction by which the registering device in its operation by the numeral-key is caused to overthrow slightly, so as to avoid the possibilit of not. giving it suflicient movement, an subsequent to the disconnection of the registering mechanism from the key the registeringdevice is given a reverse movement independ-' ent of'the movementof the key sufiicient to correct the overthrow and leave the registering device finally in its true position.

The invention of the present application includes improvements in the carrying mechanism and in the tri ping devices and the means for shifting til eludes also improvements in the opera't g and register-actuating mechanism, as hereinafter more fully disclosed; and the invention consists in the construction and combine? tions of elements hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective View showing the invention in position on a type-writing machine, the front plate being partly broken away, so as to show one of the series of registering devices with its actuating and operating'mechanism complete, parts belonging to the other registering devices of'the series not beingsshown.

Referring to. the drawings, 1 indicates the frame of the type-Writing machine.

2 indicates the keyboard.

3 indicates the paper-carriage, and 4 indicatesthe top plate.

The calculating device is arranged, as in my atent above referred to, directly in rear of t e keyboard and is secured to the top plate 1. Inv order to provide a proper place or t he calculating device, the rod 20 of the I nechanismis. bent downward, as shown. As in my patent before referred to, the calculating device comprises end plates '5, secured to the top plate &, connected by rods.v and, serving to support the shafts and rods. on. which. the operating arts are carried', and a front plate 6,'suita ly secured to the end, plates.

The main shaft 7 is substantially the same as in my patent and,'.as shown in Fig. 3, is provided; at oneend with sprin 8 for returnmg it to normal position an with radial arms 9. The radial arms are slightly adjustable and are-held in. position. by setscrews 1 0. The stationary sleeve 11 surrounds the shaft 7 concentric therewith and is Fig. 14 is a deprovided with the slots 13, as shown in Fig. 2 in, which the radial arms 9 move. ()n the sleeve are supported the devices by which movement is transmitted to the radial arms 9 and the devices by which the movement of the radial arms may be transmitted to the registering-wheels.

The registering-wheels 16 are carried on a shaft or rod 15 and are each provided with a pinion 102 and a ratchet-wheel 103. In the present device, as in the device of my patent, it will be understood that a registering-wheel is provided for each order of digits and separate actuating devices are provided for each registering-wheel. It will also be understood that the registering-wheels are arranged with the units-wheel at the right. As in my patent, I have shown nine registeringwheels, though a greater or less number may be used.

In the present invention, as in my patent,

the numeral-keys when depressed rock the main shaft without effecting any movement of the registering-wheels unless by the action of the tripping device the actuating mechanism of one of the registering-wheels is thrown into position to be operated by the radial arms 9. In the construction of the tripping devices and as in the construction of theactuating devices for the registering-wheels, as well as in other features of construction, my present invention differs from that of my patent. The tripping-arms 18, Figs. 15 and 26, have their bearings on statlonary rod 17, which is located to the rear of and slightly above the rod 15, Figs. 7 and 28. The tripping-arms are preferably formed of sheet metal bent at 21 to embrace the rod 17 and having the portion below the rod 17 provided with a forwardly-projectin end 22. Above the rod 17 the arm is curve forward and has at its end a lateral extension 23, by which is afforded a front edge of greater length than the width of the main portion of the trippingarm. At a point below therod '1-7 the tripping-arm is provided with a finger 24, which extends forward and downward, terminating in a lateral extension 25.

The tripping devices 19, Figs. 30, 31, and 32, each comprise a vertical portion 190, having at its upper end a forwardly-extending arm 191 and having a rearwardly-extending arm 192, whichv is rigidly connected with an upright 193, arranged substantially parallel with the vertical portion 190 and provided with a notch 194, Figs. 7, 8, and 28, which embraces the front edge of the .upper end of the tripping-arm 18.

The tripping. devices are so located that their arms 191 will lie in the path of a tripping-cam 133, carried by the paper-carriage. The upper edges of the arms 191 are preferably beveledfso. that the tripping-cam will readily depress them.

- tionary rdd 1 Within boxes 197 are each open open ended guide-slots 195, which fit over a sta- 196, secured at its ends in the end plates 5.

The vertical ortions 190 of the tripping devices'are eac inclosed ina box 197, in which they are free to move vertically. The at the top and back and are rovided near their upper and lower ends .wi-t openings which fit over rods 198.

the boxes 197, Figs. 30, 31, and 33, the vertical portions 190 are ea'ch provided with a shoulder 211, against which bears the upper end of a spring 212,-the lower end of the spring-bearing a ainst a screw 213, which engages the sides 0" the box and by which the tension of the spring may be adjusted. The spring serves to hold the tripping devices. normally in elevated position.- At its lower end each; of the vertical portions 190 is provided with a stop-lug 214, which engages the undersideof the lower rod 193. As in the machine described in my pat'ent'before referred to, it is- -son1etimes desirable toseparate the jboxesm groups to allow for the printing of the commas between certain num-v bers, as between dollars from left to righta -re prevented from moving on the rods by pins 199, Figs. 32 and 33.

The other boxes are free ;tobemoved to and 198 are carried by ing forward from a plate-201 which is secured.

I to a bar 202, which is fastened at its ends to ,longitu'dlna'l vmovement thereon and 1s, ro-'.

7 The end holes, three in number, to receive the in 1 against accidental 'fifth boxes above Each of the boxes except the fourth and with 8, rearwardly-extending lug sleeve 206, Fig.

. has hearings in plates 5.

Ea'ch ofjthe rods 198 carries a spring 203,,bearing atone end againstone ofthearms. 200 and at the 'other end, bearing against -a plate 204, carried by the, rods 198, and bearing against the outer one of the boxes-197.; These springs'norrnally hold the movable boxes against the fourth and mentioned.

th is provided about midway of its length 205, Figs. 31 engages a cam-groove in a 6, carried by shaft 207, which the arms 200 and in the end .On one end exterior to the end late this shaft is provided with 'a milled head 208 for rotatin 'it. The milled head is t so as to be capable of and '33, w 'ch mounted on the sha vided on itsinner face with a pin 209, Fig. 18., plate is provided with a series of 209. A spring 210 serves to hold the mil ed head against the end plate with the. pin 209 in one of the holes, thus locking the shaft rotation. By drawing the milled head outward against the force of, the spring 210 the pin 209 is freed from en-- .ga'gement and and cents and hun dredthousands.

horizontal portions of tending the milled head and shaft may be rotated to shift the position of the mov able boxes.

The sleeve 206 bears at its end against the inner faces of the arms 200 and is secured to the shaft 207 by screws, as shown. The camgrooves in the sleeveare so formed that when the shaft is rotated in one direction the three boxes-at the left will be moved bodily to the left one space and thethree boxes at the right will be moved bodily one s ace to the right, so that the boxes will then of three each with a space between each group, and the cam-grooves are so formed that when the shaft is rotated in the o o e in three groupssite direction the two boxes at the left wil be moved bodily one space to the left, the righthand boxfwill be moved two spaces to the right, and the next three boxes will be moved one space to the right, so as to leave the boxes in four groups of two, three, three, and one box, respectively, with a space between each group. i 1 4 The firstarrangement is intended to provide a 'spacefor printing a comma between each group of three digits to separate thousands from hundreds and millions from hun- The second arrangement is intended for use in printing figures representing dollars and cents, the space between the group oftwo at the left and the adjacent group being intended for printing the decimaloint, the spaces between the othergroups ein'g intended for printing .commas.

The rea'rwardly extending arms 192 of the trippingdevice, which is in. the center of the group, extends directly backward to its upright 193. The arms 192 of the tripping de- IOC vices to the'right of the center -of the group extend rearward from the vertical portions '190-from points above the shaft 207 and are connected with their uprights 193 by horizontal portions of varying length extending to the right, as shown. Thearms 192 of the tripping devices to the right of the center of the group extend rearward from the vertical portlons 190 from points below'the shaft 207 and are connected wlththeir uprights by' varying length exto the left, as shown.

, ln s ifting the vices, as above described, the uprights 193 will slide horizontally relative to the ends of the tripping-arms, a sufficient movement be- 1ng. permitted without disengagement bv reason of the length extension 23. w

The tripping-cam 133, Figs. 1 and 29, is formed on the'end of a bell-crank arm 134, pivoted at to a plate mounted to slide on a bar 136, connected by arms 137 to the aper-carriage. The plate 13, to which the bellcrank arm 134 is pivoted is provided with suitable means for engaging the bar 136 and is also provided with a spring-arm 138, se-' of edge afforded by thb position of the tripping de- &

cured to it at one end and having at its free end a detent 139, adapted to engage teeth on the upper edge of the bar. A lug 140 on the plate extending above the free end of the spring-arm 138 permits the detent tobe. raised sufficiently to disengageit from the teeth ofthe bar and at the same time protects the free end of the arm against being raised sufficiently to endanger its breakage.

The vertical. arm of the bell-crank lever 134 is provided with a cam-surface with which engages the end of an arm 141, pivoted to the plate and provided with a-forwardlyextending finger-piece 142. A spring 143, connected at one end to the pivot of the arm 141 and at the other end bearing against the horizontal portion of the bell-crahk lever, serves to normally depress the tripping-cam into position to act on the tripping devices 19. By lifting the arm 141 by the finger-- piece 142 the bell-crank lever is turned on its pivot to raisethe tripping-camput of pc- I sition to act on the tripping devices.

The machine should be provided with two or more tripping devices, any one or all of which may be used, as desired.

The rocking plate 29, Figs. 1, 2, and 19, is pivoted, as -in my patent'before referred to, at its ends to the end plates 5 near their lower endsand near their front edges and has a rearwardly-extending arm arranged to contact with the shaft 32 when the rocking plate is in normal position. The stop-ar ms 30 are preferably. formed integrally with the rocking plate, and to theinner face of the rocking plate are secured the slotted arms-31.

In connection with the'mechanism for op-' crating each of the registering-wheels I provide a lever 33, journaled on a collar 11, se-- cured to the stationary sleeve.

. movement of the levers longitudinally of the shaft, each lever has connected with itan'arm 34', which is also journaled on the collar, the collar having between the bearing. of the lever and arm' a portion of'greater diameteri than the bearings; One of the levers 33 is arranged in proximity to one'of' each pair of the radial arms- 9, and each of the/levers is provided with a-lateral projection 35, adapted to engage the rear of the arm 9 and'carryl it forward with it, rocking the main shaft 7.

Each of the levers-33 is rovided with a pin-or roller 86, adapted w en the lever is drawn downward. to enter the slot 87 of the slotted'arm 31, and thus to cause the rocking. plate 29 'to rockon'itspivots to move the end of the stop-arm 3O rearward into the path of the re ister-actuating mechanism to effect the loc ing of the segmental rack and the disengagement of the. register actuating mechanism from the. mechanism operated by the depression-of the numeral-key, as-hereinafter described.

, Theshape of the cam-slots 87 inthe several arms 31 differ according to the numeralvalue To prevent of the key which corresponds to them, so as to move thestop-arm the distance necessary in each case. (See Fig. 34.) The slot'in the shape-that the rocking plate will be rocked immediately uponthe entrance of the pin 86 into the slot'sufliciently tomove the end of the stop-arm into position to eflect the locking of the segmental rackas soon as the segmental rack hascaused the'registering-wheel to-rotate one space, while the slot in the arm corresponding to the "9 key will be so shaped as to cause only sufficient movement of the rocking plate tomove theend of the stop-arm into pcsitionto cause the locking actionto take place'when the segmental rack hascaused the register wheelto -rotate nine spaces.

The projections -35'will be so positioned on the several leversas to effect'a movement of the radial a-rm corresponding tothe different numerals.

To provide for a full stroke of the addingkey when once started there extends downward from each of'the levers33 a toothed segment 36, Fig. 19, which asthe lever is rocked engages-adog'37, pivoted on'stationary rod 32 and having a tailpiece. 38, to which a sprin 39 is connected, the other end of the spring eing connected to stationary rod 77. As-the lever is rocked the=dog engages-the teeth of the segment and prevents its return movement until the lever'is depressed its full stroke. Asthe stroke iscomplete the segment passes beyond the point of the dog, and asthe lever returns to normal position the segment swings the point of the dog'in'the opposite direction and'passes-freely over-it.

To disconnect the adding mechanism from thetype-w-riterkeys, there isprovided the following mechanism: Near 'theffront' end of the lever 33 Fig; 19, and'preferably between it} and the arm 34-is-pivotally connected the upper end of link 4-1 connecting the lever with'one of 'the numeral-keysof the typewriting machine: Thelink comprises an'upper part 42' anda lower-part 43, having a screw connection. The lower part 43- of the link is=provided near its-lower end with an open slot'45, adapted to engage a pin 46, carried by'the'key-lever. The part 43' of the link is=also provided with an upwardly-extending arm 47. A- flat bar- 48', having its endsbent upward to form arms- 49, Figs. 2 and 3, the upper 'end sof which are pivoted to the end lates- 5, preferably on the outer faees-of tffeend plates, is provided with slots 48, through whiohthe arms 47 slide freely. By swinging the-bar 48- the-slots-45 of all of the-links 41 are simultaneously caused to engage the pins 46 of the numeral-keys or are disengaged therefrom, asdesired. The arms 49 being outside the end plates aiford convenient means for swinging-the her:

arm corresponding to the 1 key is of such so. ceived the pawl-carrier 51.

The device bywhich the rocking of the main shaft is caused to actuate the registerwheels are arranged in groups corresponding in number with the registering-wheels. Each group comprises a bearing-piece 50, Fi 15, supported on and free to rotate on the sleeve 11, a=pawl-carrier5l-, Fig. 16, arranged to rock on the bearing-piece and carrying vpawl 53, a awl-carrier 52' carrying pawl 54, a

re cam-p ate between the pawl-carriers in proximity to the pawl carrier 51," and a segmental rack56 in proximity to the pawl-car rier 52.- 1

p The bearing-piece 50, Fig. 15, is circular in cross-section and comprises an outer portion 57, a central portion 58, a flange 60, and a non-cylindrical portion 59, Fig. 24. Be-

tween the portions 57 and 58, Fig. 15, is

formed an annular groove 57 in which is re- In the rear'of the portion 58 is formed a recess 58, in which is plvotally secured the upper end of a de-' pending arm 150, .Fig. 7,. the' lower endof. I which is connected. by a spring 151 to the. rod '2 5 ,77. Between the portion 58 and the annular flange 601 is formed an annular groove- 59, which receives the camplate 55., Against the opposite face of the annular flange 59 the se ental rack 56 is placed.

o hepawl 53 is pivotedto the rearward ex-Q tension 62 of the pawl-carrier 51 and is so-lo eated that its forward hooked end 63 is in the plane of one of the radial arm's'9, so that when depressedthe hooked end will be en- 3 5 gaged' by the end of the arm. The pawl-car .rier 51 is provided in rear of the main shaft.

with a depending arm 64 of such length that 'when'the pawl-carrier is in normal position the end of this arm will rest a ainst the stao tionary rod 32. The bearingo the pawl-carrierlis 0 en downward, so that it may be readily aced in position in thegroove .57 in assemb mg the parts. Above its bearing the pawl-carrier is provided with a laterally-ex- ),5 tending finger 78 in the path of the radial -arm 9 beneath the pawl 53. I g

The pawl 53 is provided with a tailpiece 65 directl below its pivot, having its end bent lateraliy into the plane of the pawl-carrier and ada ted to contact'withthe rear ed e of the paw -carrier. At its front end, a 'ove the hook 63, the pawl 53 is provided with an I upwardly-extending finger 66. The pawlcarr'iers 51 areeach located in-front of one of the trip ing arms 18. When in normal p0 sition, t e pawl-carrier rests with its arm 64 against the .statiohary rod 32 and with the tailpiece 65 of the pawl against the lower end 22 of the tripping-arm, the position of the tripping arm being such that by contact of its end 22 with the tailpiece the forward end of the pawl will be held in elevated position out of the path of the end of the radial arm 9. -When the tripping-arm is moved by the depression of its tripping device 19, its lower the pawl-carrier is pivoted the pawl 54, Fi ,9. The forward arm of this dpawl is slight y end is swung back out of contact with the tailpiece 65, and at the same time the lateral extension 25 of the finger 24 strikes the finger 66, depressing the forward end of the pawl so that its hooked end 63 will lie in the path of the end of the radial arm.

.On the side next the cam-plate 55 the pawlcarrier is provided with a roller 67, Fig: 17, v

for the purpose of lifting the cam-plate. 1

The cam-plate 55, Figs. 12 and 13, has its upper edge curved, as shown, the edge being bent over toward the pawl-carrier 51 to form a flange 68. The rear end of this flange is bent upward, as shown at 69. The camplate has its bearing in annular groove 58 of the bearing-piece and is formed withan ov en 1 The segmental rack 56 carries on the side next the-:cam-plate a roller 74, Fig. 8, so

laced as to ride on the flange 68. The rack'ig 5 as an opening 75 formed therein, adapted to -fit-over and slide on the non-circular portion 59 of the bearingiece 5().' At its lower end pp the rack is provi ed with a stop-finger 76,

which whenthe rack is in normal position loo contacts with-the rod 32.- The rack has on its upper'edge ten teeth, adapted when\the rack is" raised into operative position to mesh withthe teeth of the pinion 102-of the registering wheel." I

The segmental rack is provided with a rearward extension having a laterally-bent end forming a finger 73, which liesabove the tai ipiece 82 of the pawl 54. he pawl-carrier 52 is secured by a screw or rivet 80 against the face of the non-circular portion 59 of the bearing-piece, confining the segmental rack between it and the annular flange 60. To the upper rear-portion of longer than the pawl 53 an has a hooked end 81 ada ted to be engaged by the upper end of a re 1al arm 9. This pawlhas'a tailpiece 82, which when the parts are in normal position lies immediately above the finger 72 of the cam-plate'and immediately below the finger 73 of the segmental rack. Extending upward from the pawl near itspivot' is a finger 83.

. arm 84. 'At its upper end the arm is provided with a rearwardly-extendin g finger 91,

n adapted-to contact with the finger 83 of the pawl 54. The arm 90 is provided with apin 92, which plays in the canrslot 86 of i he arz'n 84. A spring'93, coiled about a pin 94, secured to the segmental rack, bears at one end against a pin 95, secured to the pawl-carrier 52, and at its other end bears against a pin 96 on the arm 90 l 0 hold the arm 90 normally in its forward-position, the spring also serving to hold the segmental-rack normally in depressed posit ion.

A stationary rod 26', supported at its ends in the end plates 5, extends across the m.- chine forward of and below the shaft.- 15, which carries the registering-wheels. On this rod 26 are rigidly secured rack-plates 97, the rear ends of the plates being secured to the stationary rod 17. One of the rackplates is located directly in front of the arm 84 ofeach'of the register-actuating devices. The under edge of the rack-plat e opposii e the arm 84 is arc-shaped and is provided with teeth 98 adapted to be engaged by the teeth 85 of the arm 84 when the free end of the latt-er is raised, as hereinaft er described. When so engaged, the arm 84 and the segmental rack 56 are prevented from moven1ent.

On the stationary rod 26 are pivoted detent-pawls 104, held by s rings 100 in engagement with the teeth of tie ratchet-wheel 108 of the registering-wheels.

The machine being arranged as shown in Fig. 1, the depression of any of the numeralkeys of the typewriting machine will, through the link 41 and the arm 33, cause the V main shaft 7 to rock, the ends of the radial arms 9 passing freely beneath the hooked ends of the awls 53 and 54, the pawl 53 bemg held in e evated position by the contact of i the lower end 22 of the tripping device with the tailpiece 65 and the pawl 54 being held in elevated position by the contact of the finger 73 of thesegmental rack with the tailpiece 82.' On the release of the key the shaft 7 is returned to normal position by the s ring 8. When the movement of the carriage brings the cam 133 against one of the dripping devices, depressing it, the trippingarm 18 is swung on its bearing,.-movmg its lower end back out of contact with the tailpiece permitting thehooked end of the pawl 53 to drop into the path of the end of the radial arm 9. This movement of the tripping-arm carries the endof the finger 24 against the finger 66 on the end of the pawl, insuring its dropping into position to have its hooked end in the path of the radial arm. The pawl 53 being thus tripped, onthe depression of any one of the numeral-keys the rocking of the main shaft will cause the pawl 53 and its awl-carrier to rock with it, bringing the rofler 67 against the cam 69, lifting the camplate 55, As the cam-plate rises it lifts with it the segmental rack, the finger 73 of the segmental rack being lifted out of the way of the tailpiece 82 of the pawl 54 and the finger 72 of the cam-plate being brought against the tailpiece 82 to depress the forward end of the pawl into the path of the end of the radial arm 9. The further movement of the rock-shaft by the engagement of the radial arm 9 with the pawl 54 rocks the pawlcarrier 52, and with it the segmental rack 56, forward. The teeth of the segmental rack being in mesh with the pinion 102, the registering-wheel is rotated until the proper numeral is opposite the sight-opening in thefront plate 6, the 'detentawl 104 engaging the teeth of the ratchet-w eel 103 to prevent rearward movement. The movement given to the segmental rack is preferably suflicient to cause the registering-wheel to overthrow slightly, so as to carry the point of the tooth of the ratchet-wheel corresponding 'to the numeral to be registered slightly past the point of the detent, not, however, suliiciently to carry the point of the next tooth past the point of the detent. By thus slightly overthrowing and subsequently bringing the registering-wheel back to true position, as hereinafter described, certainty of operation is secured even after, by continued use, the parts become appreciably worn. By reason of the engagement of the teeth of the segment 36, carried by the lever 33, with the pivoted dog 37 the lever 33 and the registeractuating. mechanism is held against reverse movement until it has completed its full stroke. As the lever 33 is drawn downward by the numeral-key its roller 86 enters the cam-slot 87 of the arm 31, secured to the rocking plate 29, causing the plate to he rocked to move its arms 30 rearward into the path of the segmental racks and the arms 90, carried by them. Before the key is fully depressed thearln 90 strikes the end of the stoparm 30, and as the segmental rack continues its forward movement the pin 92, acting on the cam-slot 86, throws the free end of the arm 84 upward until its teeth 85 engage the teeth 98 of the rack-plate 97, locking the segmental rack against further forward movemovement the shaft moves freely so far as the segmental rack and the registeringwheel are concerned. The further forward rocking inovement of the shaft carries with it to the acts on its typebar practically as freely as do the letter-keys or other keys not connected with the calculating device. The devices may be arranged to effect this freeing of the key from the register-actuating mechanism it any desired point in the depression of the ey.. w Haying completed the movement necessary' to effect the printing, the finger-key re-" turns to normal position, and with it the rockshaft under the influence of spring 8 also returns to normal position. 'As the lever 33 rises, carrying it's pin 86 upward in the camslot 87, the rocking plate 29 carries the end of the stop-arm 30 forward away from the arm 90. 1 The arm 90 is thus free to be tilted forward on its pivot by the spring 93 carrying its pin 92 downward in the cam-slot 86 of the arm 84, permitting the free end of this arm to f ment with the teeth 98 of the rack-plate 97,

thus unlocking the. segmental rack, the segmental'rack remaining in its elevated position with its teeth in engagementwith the pinion 102. "The spring 151, "acting through the arm 150, pivotally connected to the bear ing-piece, draws the segmental rack backward, rotating the pinion 102 and the registering-wheel backward until its further backward movement is preventedby the pawl 104. This brings .the registering-wheel back to true position, with the'proper numeral in line with thesight-opening, correcting the overthrow previously given to the registering-wheel, as abovedescribed. the'further return movement of the rock-shaft the radial arm 9;aeting against the finger 7-8- carries the pawl-carrier '51rearward, and as r the roller" 67- of the pawl-carrier passes back ward frombeneath the flange 68 of the camplate the cam plate, and'with it the segmental rack, drops under the influence of the spring 9 3, withdrawing the teeth of the rack from the'pinion 102. The segmental rack and pawl-carrier. 52 are thus-free to be returned to normal position by the spring 151 acting through the arm 150.1 'The segmental rack being disconnected from the devices operatedbythe key'before the completion of the depression of the key and remaining disconnected during the return of the several partsto normal position, the return. of the key to normal position is eflected quickly and the machineis ready' to be again operated by the depressionof a key without'waiting for'the The shaft a radial pin 105, Figulo, having its end bent laterally, and is also provided with a cam 106.

Carried by the stationary rod 27, so as to rockfreely thereon, is a double-armed carrying-pawl 28, Figs. 11, 20, 22, and 23, the arm 107 being arranged to be operated by the radial pin 105 and cam, 106 ofa lower registering-wheel and the arm 108 being arranged to effect the operation of the next higher registering-wheel. The double-armed pawl is provided with a finger 29, extending forward and upward," as shown. The arm 107 of the carrying-pawl 28 is forked, the end of its lower finger 109 being; arranged in the path of the end of the arm 105 and its upper finger 110 having its end. bent laterally into the plane of the cam 1'06. A collar 117 is secured' to the rod 27 between the arms 107 and 108 of the pawl 28.

at its end is forked to fit over the shaft 15. A spring119, coiled about the rod 27 and engag ing the finger 29", is arranged to'press the forward ends of the arms 1-07 ward.

, To'the forward end of the arrn 108 is pivoted the upper endof a pawl 111, arranged in, the plane of the ratchet-wheel 103 ofthe higher registering-wheel and provided. with a tooth 112--for engagement therewith. The .upper end of the'pawl 111 above its pivot is provided with a rearwardly-extending finger 113, a ainst which a fiat spring 114 presses to From thecollar an arm' 118 extends forward and downward and.

and 108 'dow1'1- hold t e lower end of the pawl normally in forward position. In rear of the tooth 112 the pawl 111 is notched at 115, and it is provided with a depending finger 116, ofiset out of the plane Of the tooth 112. The camplate 55 is provided in rear of the cam 68 with an upwardlyextending arm 120. To the upper end of this arm is pivoted the end of the horizontal arm 122, Flg. 21, of an elbow: lever 121, the upper'end of the vertical arm 123 of the lever being pivoted to the arm 118.

The connection of the arm 122 with the arm 120.i s formed by a pin on the arm 120 ex tending through ahorizontal slot in the arm 122, so that the Mm 122 may move rearward on its pivot, but moves with the arm 7120 when the cam-plate carrying the latter is raised. The arm 123 ofthe lever 121 is offset at 124 out of the plane of the arm 122 and is provided near its juncture with the. arm

122 with a laterally-bent lug 125, between which and the offset 124 the depending arm 116 of the pawl 1 ll isxguided.

The arm 122 is provided with a pin 1%, which extends into a cam-slot 1.30 in the depending arm 128 of an elbow-lever 127, arranged inthe plane of the pawl 111, pivoted to the rack-plate 97 by a pin 131, the horizontal arm 129 of this lever extending forward the ratchet-wheel 103.

'and'adapted to fit thenotch 115 in the pawl to hold the tooth 112 in forward position in engagement with a tooth of the ratchet- 103 to lock it against movement. When the cam-plate is raised by the roller 67 of the-pawl-carrier'51, a-s-above described, the arm 120 raises the rear end of the arm 122, swin ing the arr'n122,-together with the lower emf of the arm 123, forward. By the action of the pm 126 in the slot 130 of the arm 128 the lever 127 .is rocked on its pivot to move the end of the arm 1-29 downward out ofengagement with the notch 115, leavingthe free'end of the pawl 111 free to swing rearward against the force of the spring 114. As the arm 123 swings rearward the in 125 contacts with the lower end of the Pew and carries it rearward out of engagement with wheel is thus left free to be rotated by the segmental rack. On the return of the camplate to normal positionthe pawl 111 re sumes its normal position, engaging the ratchet-wheel 103, locking the ratchet-wheel and the registering-Wheel, to which it is secured, against movement in either direction,

the arm 1296f the lever 127 engaging the notch 115 and holding the tooth in locked engagement with the ratchet-wheel.

As the lower registering-wheel is rotated by successively operating the numerabkeys to actuate its segmental rack the cam 106 gradually raises the end of the finger 110 of the arm 108 of the double-armed pawl 28,

raising with it the end of the arm 108, lifting I by the action of the spring 114, and the highest point of the cam has passed beneath the end of the finger 110, permitting the finger, and with itthe pawl 111, to drop under the influence of the spring 119, the return of the pawl to normal position being insured by the action of the end of the radial pin '105 against the end of the finger 109 of the arm 107 of the double-arm pawl. This downward movement of the pawl 111 :ro. tates the higher registering-wheel one space. The rack-plate 97 is providediin its rear-- The registering.

wardly-extending portion with a bearing 97 to receive the hub oftheregistering-wheel, the plate fitting between the registering wheel and its pinion 102, thus preventing lateral movement of the registering-wheel and also supporting it, together with its shaft 15, against downward movement. Any tendency of the shaft 15 to rise is prevented by the arm 118. i

The shaft 15 is provided with resettingpins 143, corresponding in number with the registering-wheels, of such length as to engage the laterally-projectingends of the radial pins 105. The resetting-pins 143 are so placed that when the shaft is iii-normal position they will be out of the planes of the radial pins 105; but on shifting the shaft longitudinally the resetting-pins will be each' brought into the'plane of theendof a radial pin, sothatwhen the shaft 15 is rotated the resetting-pins will strike the ends of the radial pins, and the registering-wheels being previously freed from the engagement of the pawls 1-11 with their ratchet-wheel s they may be reset'to zero. i I

The shaft 15 is provided at one and outside the end plate 5 with a milled head 144, having on its inner face a pin 145, adapted to enter an opening 146, Fig. 20, in the end plate when the shaft is in normal position. A spring 147, bearing .at one end against the inner face of the end plate and at its other end bearing against a pinon the shaft, holds the shaft normally in such position that the resettingins are out of engagement with the radia pins 105. When in this position, the-pin 145 enters the opening 146, holding 'the shaft locked. In order to rotate the shaft to reset the registering-Wheels, the milled head 144 is drawn outward against the force of the spring 147, disenga ing the pin 145 from the opening 146 and ringing the resetting-pins into position to engage the radial pins 105. 'The'shaft is then rotated-to reset the registering-wheels.

In order to free the reglsterlng-wheels to permit them to be reset to Zero,-1t 1s necessary to disengage the ,pawls 111 from the ratchet-- wheels 103. This is effected by means of abail 160, carried by arms 161 (see Figs. 7 and 8,) having bearings on one of the fixed shafts and adapted when-rocked to strike, the upwardly-projecting fingers 28 of' the double carrying-pawl. A finger-piece 162, extending through a slot in the front plate, is connected to the bail to move it'toact on the fingers 28 to rock the double-armed pawl to lift the pawl 111. v

The front plate is provided with eightholes for each of the registering wheels,

through which the number registered'rnay be seen.

Extending across the front of the'front plate and supported by any convenient means is a rotary indicator 158,- having at IIC . to be turned to indicate the relative position between the of the tripping devices.

By reason of the long horizontal arm'l91 of the tri may be shifted without disengaging ping-cam from them.

Any number of tripping-cams may be used where it is desired to print and add numbers in several columns,- the tripping-cams being adjusted on the'bar 136 in accordance with the desired position of the columns. If it is desired to add two columns separately, the device'may be used as two separate registers, using the registering-wheels in groups-as, for instance, using the first three or more of the registering-wheels as the register for one column and the remaining registering-wheels for the other column. In suchuse of the de the tripvice the total of the columns must be printed and the registering-wheels reset to zero before the left-hand wheel of either group is rotated beyond 9, bers of the first column the numeral-keys will not beoperated while the first trippingcam is in contact with any one of the tripping devices of the second group of registermg-wheels, and, conversely, the numeral-keys will not be operated while the second trip ping-cam is incontact with any one of the tripping devices of the first group of registering devices. -This use of two tripping devices with the registering-wheel. used in.

groups will be found convenient when itis ,4 desired to' place in one column-thenumber of articles so (1 and in the second column the values of the articles. The two columns may be arranged at opposite sides of the sheet and any desired matter maybe printed two columns. Where it is desired to print the nu'nbers in separate columns and to add the numbers so 1 printed, tripping-cams corresponding in numer with the number efcoluimis will be used,

the total of all thecolumns together being shown on the register. In making'an itemized statement of checks paid this arrangement will give the items in several columns on a sheet of any-width desired, ins tead of a single column on a long stri or roll.

When it is desired to print the total, the lever 141 is thrown u 'f inger piece 142,- raising the-cam 133 above tripping devices. The total shown by theregisterin 'g-wheels-may then be fward by t'ne'ans of the the plane of the and described, as it is obvious that ping devices the paper-carriageand in printing-the nu1n-.

actuatin tuating means comprisin printed by the numeral-keys without 'efiecting any movement of the registering devices.

When it is desired to use the type-writing machine for ordinary urposes, the bar 48 may be swung rearwar by means of its arms 1&9, disengaging the links from the numeralreys.

not limited to the precise construction shown in details of construction and arrangement may be made without affecting the essential features of the invention.
